1. Map Projections

2. All flat maps have some distortion in their representation of:
Distance
Shape
Area
Or direction.

3. Equal-area (or equivalent) projections: maps that maintain area but distort other properties.
Conformal (or orthomorphic) projections: maps that maintain shape but distort other properties (it is impossible to have a projection that is both conformal and equal area).
Azimuthal projections: maps that maintain direction but distort other properties.
Equidistant projections: maps that maintain distance but distort other properties.
Types of Projections

4. Mercator Projection

5. Cylindrical

6. Planar (Azimuthal)

7. Planar (Arimuthal)

8. Conic

9. Conic

10. Compromise

11. Compromise

12. Combining Maps and Technology
GPS and GIS

13. Using GPS GPS- Global Positioning System Used to track routes
Used to track routes- cars/boats, etc
Can track animals (ex. migration routes)

15. Using GIS GIS- Geographic Information System
Technology that uses digital map information to create a databank
Different data layers can be combined to produce specialized maps.
Used to analyze to solve problems

16. File info into your brain!
As new technologies link people all over the world, having an understanding of geography is more important than ever. Do you agree? Why or why not?
